Everything is an illegal request

First, can't get past the setup Screen, "illegal request" error.
Do a refresh and the Dashboard appears, but broken with another "illegal request" error.
Clicked on the profile, then on logout. Another error came out:
{"success":false,"error":{"code":"Illegal request","message":"Illegal request","title":null}}

Feels like the anti-CSRF code going amok
